[The exercise test in adolescents].
Arterial hypertension is characterized for abnormalities in its different stages, progressing from a hyperdynamic stage with increased volume and cardiac output with a normal peripheral resistance to increased in peripheral resistance and normal cardiac output in established hypertension. During childhood and adolescence, the risk for developing hypertension, because of a positive family history or high normal values of casual Blood Pressure (BP), could be detected according to the BP response to exercise during a treadmill test. It may be necessary to begin non pharmacological or even pharmacological treatment in patients with abnormally high values. Adolescents with normal casual BP may have abnormally high BP with exercise, while some of those with high normal BP at rest, will have normal BP response to exercise. Additionally, treadmill test, will allow to determine the level of exercise secure for each adolescent and to measure the conditioning effect of exercise.
